Study finds link between heart failure and kidney disease
Advertisement
Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, have found links between heart failure and kidney disease that could support new approaches for integrating the care of these conditions.
The results were published in JAMA Cardiology.
About two-thirds of older adults with heart failure have abnormal kidney function. However, few analyses to date have investigated the occurrence of clinically relevant kidney outcomes, such as hospitalization for acute kidney injury or dialysis, in patients with heart failure. Evaluating these more recognizable and patient-centered outcomes may result in substantial changes to the way that heart and kidney disease are managed together in the clinic.
The study examined Medicare claims data from 85,298 patients over 65 who were hospitalized with heart failure between 2021 and 2024, using data from the Guidelines-Heart Failure Registry.
Researchers found that 63 percent of these patients were discharged with significantly impaired kidney function, measured by their filtration rate.
They also discovered that patients with lower kidney function had a much higher risk of adverse kidney outcomes. One year after discharge, 6 percent of patients were on dialysis, and 7 percent were either on dialysis or had progressed to end-stage kidney disease.
